CONTROLLING DEVICE.

Specification of Letters fiate'nt.

Patented Aug; 11, 1914..

Application met my '15, 1912. term We. 69?,4'232.

To all whom it may concern Be it known that I, NELsoN C. DURAND, a citizen of the United States, and a resident of the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Controlling Devices, of which the following is a description. 7

My invention relates to' controlling devices and especially to controlling devices for business or other phonographs.

The objects of my invention are to provide improved, simple, and efficient means for controlling the starting and stopping of phonograph or other mechanisms; and to provide controlling devices for a phono giaph having means serving as a handle for the sound conveyer thereof, whereby the sound conveyer may be supported in and moved to any desired position, and the controlling device may be actuated, by the hand of the operator;

More specifically described my invention comprises pneumatic means preferably con- 'sisting of two pumps connected by flexible tubing, one of the pumps beipg preferably -T connected to a clutch between the driving and driven mechanism of aphonograph and.

i the other pump being preferably connected section, of the actuating to the sound conveyer of the phonograph and serving as a handle therefor, the sound conveyer being preferably formed with afiexible portio In order that my invention may be more clearly understood, attention is directed to the accompanying drawings, forming a part of this specification in which the same reference characters are used to designate corresponding parts throughout and in which:

Figure l is a view in perspective show ing a phonograph with my invention applied thereto; Fig. 2 is a front elevation, partly broken away, of the driving and driven mechanism of a phonograph, the clutch between the drivin and driven mechanisms, and the means for controlling the clutch; and Fig. 3 is an elevation, partly in pump of the controlling device which serves as a handle for .the sound conveyer.

Referring to the drawings, reference numeral 1 designates a phonograph comprising the phonograph mechanism 2 and the driving mechanism 3. The phonograph mechanism is adapted to be driven by the driving mechanism 3 through a clutch comably comprises a hollow member prising a shiftable clutch member 4. Movement of the clutch member 4 in one direction or the other serves to connect and disconnect the driving and phonogra h niechanisi'ns. The p onograph is provided with the usual sound bo'x carrier arm or carriage on which are pivotally mounted the reprod mer 5 and recorder 6 forming parts of the phonograph mechanism and either of which is adapted to be brought into operative position with respect to the record blank 7 carried by the mandrel 8.

Reference character 10 represents the usual guide rod for the sound box carrier arm or carriage. One end of a sound conveyer 9 is adapted to he slipped over the neck of either the recorder or reproducer. The sound conveyer preferably comprises an intermediate flexible portion 11 and an outer ri idportion 12 terminating in a bell or mout piece 13. I provide suitable means for controlling the position of clutch member 4 and thus the stopping and starting of the phonograph mechanism which means preferably comprises a bell crank lever 14 aving a loose connection with the clutch member 4, a pneumatic device and suitable connections 16 between the bell crank 14 and the pneumatic device. The pneumatic device preferably consists [of a pump 17 mounted on the phonograph frame, a second pump 18, and means connecting the pumps comprising a flexible tube 19' con nected at one end with the pump 18 and a detachable connection 15 between the other end of the tube 19' and ump 17, The piston 20 of the pump 17 is connected by the connections 16 to the bell crank lever 14,

and this piston --is adapted tobe moved to actuate the connections 16, bell crank'lever 14, and clutch member 4 by the changes in pressure in the column of fluid in the tube 19'.

Referring to Fig. 3, the pump 18 prefer- 19 having a preferably enlarged portion forming a cylinder 20 and an elongated portion 21, a spring pressed piston 22 1n the cylinder 20, and a rod 23 connected to said piston and extending out through the end of the elongated portion 21, and having a button or thumb-piece 24 on its outer end. The elongated portion 21 of pump 18 is of such a size as to be gripped or held by the hand of the operator while allowing the operator to actuate the rod 23 by his thumb as shown in Fig. 1. The pump 18 is preferably rigidly connected to the rigid portion 12 of the conveyer to serve as a handle therefor by any suitable means, as by brackets 25.

When not in use the sound conveyer and pump 18 will depend from the phonograph, but when it is desired to use the phonograph the operator 'grzasps'the handle or" elongated portion 21 of pump 18, moves the sound conveyer 9 to the desired position, and presses on the button 24 to startthe phonogra h, mechanism .On applying pressure to t e. button 24:, piston22 Will be'forced inwardly;

against the spring 26 and compress the fluid '1'5Qi-n tube 19' and thus actuate the piston '20 ofthe pump '17, connections 16, and 'bell crank lever 14 to shifttheclutch member 4. into a position to operatively connect the driving mechanism 3" and phonograph mech- 'anism .2. Upon release of the pressure on button 24 spring 26 will force the piston 22 to the position shownin Fig. 3, a'nd suction will cause piston 20, connections 16, bell crank leverg14, and clutchmember l to as-.

'25 suing the positions shown in Fig. 2, and dis% connect the driving and phonograph mecha nisr psf I I F lthough Lha ve illustrated my improved controlling device as .applied to a phono to; ,graph itvvill of; course'be understood that it may beadapted. for use in numerous other a Having novvdescjribed my invention, what I claim; and desire to protect byLetters Pat-. 'ent isz;

. ,1. In.a devic e' of the classdescribed, the

"pombination with phonograph mechanism .'and operatin'gfmeans therefor, of a sound bonveyer having a mouth iece and connect a 10 'edf'to the phonograph mec anism, and a de-' yi ce appl ed 1 to said sound .conveyer and co'mprisin .a inember constituting a handle,
